。Both oil and water are used as lubricants for plain bearings. The problem with IN+ for Ura rfj is to install a tight packing device. Leakage of oil into the environment must be avoided even from the point of view of nature conservation, and on the other hand, the intrusion of salty seawater into the bearing arrangement may result in bearings that have not been manufactured to withstand the oxidizing effects of saltwater. Easily causes corrosion effects on the elements. On the other hand, bearing devices based on oil lubrication -
Cheap materials can be selected to be used as bearing materials, so there is no slippage! It is significantly more advantageous in terms of cost than four stomachs.

漏洩し、ｔｈｊ水は、軸受装置に侵入する。Oil! To make the I-slide bearing tight, various elastic ring packings or metal packings were used between the stationary and rotating elements. Generally, the rrJ lubricant in the shaft tube is connected via ducting to the f1 lubricant tank, which is installed at a high height and thus provides static pressure that reduces water leakage into the interior. It is possible in this way to provide satisfactory tightness with conventional equipment when moving through warm water under normal conditions. However, maintaining tightness is more difficult when navigating through icy water. Due to the low temperature, the viscosity of the 11'/R oil increases, so that hydraulic vibrations in the shaft tube are slowly transmitted to the oil tank, which serves as an expansion chamber. Furthermore,
It has been found that fairly high pressure oscillations with high pressure peaks occur in the tubes of the propeller shafts of ships moving through icy water. The main reason for this phenomenon is the impulse-like motion transmitted to the propeller shaft when the propeller strikes the ice block. The repeated underpressures and overpressures then tend to squirt through the packing, thus causing oil to leak into the environment and thj water to enter the bearing arrangement.

要であった。Historically, 11 problems with oil lubrication are exacerbated in extremely cold conditions, and natural hazards such as those caused by possible oil leaks are then multiplied. For this reason, oil-lubricated bearings were not considered suitable for e.g. arctic river icebreakers, and instead it was necessary to use -W1 expensive water-lubricated fittings.

Thereby, the ability of an almost frictionless gaseous medium, such as air, to react rapidly to pressure changes with a corresponding change in volume creates a desirable equalization of the pressure in the lubricant.

Lubricant is supplied to the axial tube via an inlet 14, from which oil is circulated via an outlet 15. This results in
The pump device mixes or diffuses small air bubbles in a known manner into the lubricant delivered to the shaft tube. Alternatively, or in addition, a separate source, such as compressor 16, may be used to deliver gas directly to the tube. Thereby, the gas must be delivered to the shaft tube in close proximity to the packing to be protected. When utilizing separate compression vs16 in connection with the lubricant circulation system,
121 The outflow of the lubricant should preferably be located at the same end of the shaft as the gas supply device, so that according to FIG. send.

It is essential that the pressure equalizer is placed as close as possible to the packing member, since this also reduces the efficiency of the pressure equalizer as a result of the friction binding. Of course, it is possible to arrange other similar specific force balancing devices in connection with the packing member 7, but this measure is more rarely necessary.
